Erasing the DTC Memory
To erase the DTC{S) from the SRS unit, use a Honda
PGM Tester (see the Honda PGM Tester SRS Vehicle
System Supplement) or the following procedure.
1. Make sure the ignition switch is OFF.
2. Connect the SCS service connector to the MES con,
nector (2P). Do not use a jumper wire.

3. Turn the ignition switch ON (ll),
4. The SRS indicator light comes on for about six sec-
onds and then goes off. Remove the SCS servjce con
nector from the MES connector {2P) within four sec-
onds after the SRS indicator light went otf.
5. The SRS indicator light comes on again. Reconnect
the SCS service connector to the MES connector(2P) within four seconds after the SRS indicator lioht
comes on,
6. The SRS indicator light goes otf. Remove the SCS
service connector from the MES connector (2P)
within four seconds.
7. The SRS indicator light indicates that the memory is
erased by blinking two times.
L Turn the ignition switch OFF, and wait for ten sec

Troubleshooting Intermittent
Failures
lf there was a malfunction. but it doesn't recur, it will be
stored in the memory as an intermittent failure, and the
SRS indicator light comes on.
After checking the DTC, troubleshoot as follows:
1. Read the DTC (see "Reading the DTC").
4.
Erase the DTC memory (see "Erasing the DTC
Memory").
With the shift lever in neutral, turn the ignition switch
ON (ll), and let the engine idle.
The SRS indicator ljght comes on for about six sec-
onds and then goes off.

lt--- _l
Shake the wire harness and the connector, take a test
drive (quick acceleration, quick braking, cornering),
and turn the steering wheel fully left and right, and
hold it there for five to ten seconds to find the cause
of the intermittent failure.
lf the problem recurs, the SRS indicator light will
stay on.

Problem recurs, light stays on.
6. lf you can't duplicate the intermiftent tailure, the sys-
tem is OK at this time.
